Answer:
X= 1/9 decimal form x=0.1
Step-by-step explanation:
3^x+1=3²(5x)
x+1 =2(5x)
solve for x
x=1/9
Exact form: x= 1/9
Decimal form x=0.1
Answer:
Step-by-step explanation:
First you determine the variables x and y as:
x: the value for student tickets
y: the value for chaperone tickets.
Knowing that student tickets cost $ 2 more than companion tickets, it is represented by the equation:
x= y +2
On the other hand, there were 59 students and 6 companions. And the total cost of admission for the group was $ 508, that is to say that what all the students and the companions have paid adds up to $ 508. Expressed by an equation:
59x + 6y = 508
Then the system of equations to solve and thus obtain the price of a student ticket and the price of a companion ticket is:
Solving for x, the price of a student ticket:
Rearranging the first equation,
y = x - 2
Replacing in the second equation and solving for x:
59*x + 6*(x -2)=508
59*x + 6*x -12=508
65*x -12=508
65*x= 508 +12
65*x= 520
x=8
The cost of a student ticket is 8$
total cost = .25m + 25d
M is the number of miles driven and D is the number of days the car was rented
I entered into a graphing website and this is what I got. :)
Rita's error is in the sign of 2.75 in her equation. If x is her selling price, Rita needs to find the value of x in
.. 8(x -2.75) = 78
That value will be
.. x = 2.75 +78/8 = 12.50
